MSR Thru-Hiker Mesh House 1 vs Outdoor Research Helium Bivy

Two shelters, measured against each other on the figures that decide whether they work on a bike.

The short answer

The MSR Thru-Hiker Mesh House 1 is ahead on weight, floor space and price. Nothing published here goes the other way.

Assembled from the differences below rather than written over them. Every figure is a published measurement or computed from one — nobody here has used either one.

Where they differ

4 of the 4 things we can measure come out differently.

Poles to carry

the Thru-Hiker Mesh House 1 has no pole set at all, the Helium Bivy does

None — trekking-pole shelter

A trekking-pole shelter has nothing to fit across your bars, which removes the constraint entirely — but you then need poles from somewhere, strapped to the frame or bought separately. It is a different problem, not a smaller one.

Minimum weight

231g lighter on the Thru-Hiker Mesh House 1

280g
Outdoor Research Helium Bivy
511g

Trail weight where the maker publishes one — fly, inner and poles, without the stuff sacks or the footprint. Worth reading against the pole length rather than instead of it: a Bikepack edition is usually a few grams heavier for shorter poles.

Floor area

0.39m² more floor in the Thru-Hiker Mesh House 1

223 × 84cm — 1.87m²
Outdoor Research Helium Bivy
208 × 71cm — 1.48m²

Inner length by inner width as published. On a bike trip the floor also has to take whatever you brought inside off the bike, so a few centimetres is not nothing.
